Small-angle polishing machine

Technical Field

The invention relates to a polishing machine, in particular to a small-angle polishing machine.

Background

Generally, after a metal workpiece is machined and formed, burrs or scratches are formed on the surface of the metal workpiece, so that the metal workpiece is affected to be used, and therefore, a polishing machine is required to perform polishing treatment on the surface of the metal workpiece. The existing polishing machines mainly comprise circular tube polishing machines, disc polishing machines, numerical control polishing machines and the like, are mostly suitable for polishing large-area metal pieces, and are not suitable for polishing small-area planes, cavities, arc surfaces, fine gaps, included angles, groove surfaces and other narrow positions of the metal pieces.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides a small-angle polishing machine, wherein a polishing abrasive belt is arranged through a small-diameter roller, and small-area planes, cavities, arc surfaces, thin gaps, included angles, groove surfaces and other narrow positions of a metal piece can be polished through sand on the arc surface of the roller.

In order to solve the technical problems, the invention provides the following technical scheme:

a motor base is fixedly mounted on one side of the top end of the rack, a motor is fixedly mounted on the motor base, a motor output shaft is connected onto the motor in a transmission mode, a driving wheel is fixedly mounted on the motor output shaft, a driven wheel is movably mounted on the other side of the top end of the rack, the diameter of the driven wheel is smaller than that of the driving wheel, and an abrasive belt is connected between the driving wheel and the driven wheel in a transmission mode.

According to a preferable technical scheme of the invention, the motor is a double-shaft motor, two ends of the double-shaft motor are in transmission connection with motor output shafts, driving wheels are fixedly mounted on the two motor output shafts, two groups of driven wheels are movably mounted on the other side of the top end of the rack, and abrasive belts are in transmission connection between the two groups of driving wheels and the driven wheels.
